the flier block. By means of the triangular shaped foot, the block is prevented from rocking during rotation or oscillation, whereby excessive strain on the flier wire and thread is prevented. Also by means of the improved foot construction, a substantial bearing surface is provided for engagement with the retaining bushing, with consequent uniform distribution of the bearing forces.

Referring to Figure 3, I have shown an improved flier block 10, having a removable tubular bearing 11. The bearing is provided with a triangular shaped foot comprising flanges 12, and it is further provided with a reduced portion 13 forming a peripheral flange 14 in the body of the bearing.

To mount the flier block upon the bearing, the block is passed over the reduced portion 13 and seats on the flange 14. The upper edge 15 of the reduced portion is then turned back or peened, on the inner of the two nested members comprising the flier block. In this manner, the block is securely attached to the bearing so that the block and bearing rotate in unison. When it is desired to remove a foot member from the block, the edge 15 may be turned back slightly and the bearing, together with the foot member, is then easily forced out of the flier block.

It will be understood that the invention comprehends other means for attaching the flier to the bearing; the bearing may be provided with screw threads adapted to engage with the flier block or a bayonet type of joint between the flier block and bearing, may be used.

The improved foot constructions, above described, in combination with the novel flier block construction, permits economies both in manufacturing and operation and are characterized by simplicity of installation and maintenance.

While I have shown and described the preferred embodiment of my invention, I wish it to be understood that I do not confine myself to the precise details of construction herein set forth, by way of illustrations, as it is apparent that many changes and variations may be made therein, by those skilled in the art, without departing from the spirit of the invention, or exceeding the scope of the appended claims.

What I claim is:

1. In a flier for spinning machines, including a body portion, a foot member adapted for insertion into bobbins, said foot being detachably secured to the flier body and rotatable therewith.

2. In a flier for spinning machines, including a body portion, substantially triangular shaped foot adapted for insertion into bobbins, said foot being detachably secured to the flier body and rotatable therewith.

3. In a flier, including a body portion, a removable bearing formed with a foot adapted for insection into bobbins, said bearing being rigidly attached to the flier body and adapted to rotate therewith.

4. A flier for spinning machines, including a body portion, a substantially triangular shaped foot comprising circumferentially equi-spaced flanges adapted for insertion into bobbins, said foot being removably attached to the flier body and rotatable therewith.

5. In a flier having a centrally apertured body portion, a tubular bearing removably attached to the flier body and formed with a foot adapted for insertion into bobbins, said foot comprising circumferentially equi-spaced flanges rigidly attached to the bearing.

6. A flier for spinning machines comprising the combination of a centrally apertured. body portion having a removable foot member adapted for insertion into bobbins, said foot being detachably secured to the flier body and separable screw threaded means formed with the flier body adapted to retain a flier wire thereon.

'7. A flier for spinning machines comprising the combination of a centrally apertured body portion having a removable bearing formed with a foot adapted for insertion into bobbins, said bearing being rigidly attached to the flier body and separable screw threaded means formed with the flier body adapted to retain a flier wire thereon.

8. A flier for spinning machines comprising the combination of a centrally apertured body portion having a tubular bearing removably attached thereto, the bearing being provided with a foot adapted for insertion into bobbins, said foot comprising circumferentially equi-spaced flanges attached to the bearing, and separable screw threaded means formed with the flier body adapted to retain a flier wire thereon.

9. A flier for spinning machines comprising the combination of a centrally apertured body portion, a tubular member formed with a foot adapted for insertion into bobbins, said member having a reduced portion seated in the central aperture of the body, the tubular member being rigidly attached to the flier and rotatable therewith.

10. A flier for spinning machines comprising the combination of a centrally apertured body portion, a tubular member formed with a foot comprising circumferentially equi-spaced flanges adapted for insertion into bobbins, said member having a reduced portion seated in the central aperture of the body, the tubular member being rigidly attached to the flier and rotatable therewith.

11. A flier for spinning machines comprising the combination of a centrally apertured body portion, a tubular member formed with a foot adapted for insertion into bobbins, said member having a reduced portion defining a peripheral flange on the body of the member, forming a seat for the flier when the reduced portion is inserted in the central aperture in the body of the flier,
